| Summary | 0011129: Merchant backend PATCH to /instances/foo/private does not update default_refund_delay when changed alone | ||||
| Description | When PATCHing the aforementioned endpoint and only modifying default_refund_delay, the change is not reflected in a subsequent GET. If, however, default_wire_transfer_delay or default_pay_delay are changed too, then the default_refund_change is reflected in the subsequent GET. apparently there is some missing update. i couldn't find it with my grep-fu, however. what i did find is an apparent bug in src/backenddb/test_merchantdb.c's function check_instances_equal, which checks for default_{wire_transfer,pay}_delay but fails to check for default_refund_delay. This is exactly the kind of bug i was looking for as it could explain how such an update is missed; however, a "test_whatever" file does not seem like it would affect actual runtime behavior. :/ | ||||
| Steps To Reproduce | create stonks2 instance. install jq. repeat the following line with different variable settings. WIRE=60; PAY=60; REFUND=30; curl 'https://backend.w.icmp.camp/instances/stonks2/private' -X PATCH -H 'Accept: application/json' -H 'Content-Type: application/json' -H 'Authorization: Bearer secret-token:REDACTED' --data-raw '{"default_pay_delay":{"d_us":'$PAY'000000},"default_refund_delay":{"d_us":'$REFUND'000000},"default_wire_transfer_delay":{"d_us":'$WIRE'000000},"use_stefan":false,"name":"stonks2","email_validated":false,"phone_validated":false,"merchant_pub":"GE04TYN95S5CWNBBN3GWK3W2SM0WKRBSQ6X3A4MPT4KQ02JD4A40","address":{},"jurisdiction":{},"default_wire_transfer_rounding_interval":"NONE","auth":{"method":"token"}}' && curl 'https://backend.w.icmp.camp/instances/stonks2/private' --compressed -H 'Accept: application/json' -H 'Authorization: Bearer secret-token:EYADCF1E372W34G3CZ36EQJNPTPQA7PM9AQX8V6B7W8CXVENT8ZG' | jq '{"wire": .default_wire_transfer_delay.d_us/1000000, "pay": .default_pay_delay.d_us/1000000, "refund": .default_refund_delay.d_us/1000000}' results in 60/60/30 call with WIRE=60; PAY=60; REFUND=31 -> results in 60/60/30. the change is not reflected. call with WIRE=60; PAY=61; REFUND=31 -> results in 60/61/31. now it works call with WIRE=60; PAY=60; REFUND=31 -> results in 60/60/31. proves that this is not an invalid combination which was silently rejected | ||||
